“…The proposed fragmentation pathway concerning the cluster from m/z 627.3852 (−6.2 ppm) to m/z 591.3635 (−7.6 ppm) was the opening of C-and D-cycles. This type of fragmentation is commonly observed for other polyethers [20], but was not found in either gambierone or sulfo-gambierone. The small fragments reported from m/z 289.1799 (−0.3 ppm) to m/z 121.0649 (+0.8 ppm) corresponded to the ones found in sulfo-gambierone based on our hypothesis (i.e., the double bond conjugated system that induces either a carbonyl or a hydroxyl for the right-hand side of the molecule).…”

“…In positive ionization mode (ESI + ), the chromatographic peak at 6.7 min did not present any ions with a mass related to the expected [M+H] + at m/z 1039.4931 (Figure S2C) but the ion m/z 1056.5047 could correspond to the ammonium adduct [M+NH 4 ] + of 44-methylgambierone, however, with a mass error of −14.1 ppm. In addition, the protonated molecule, sodium adducts and several in-source water losses commonly observed for gambierones, ciguatoxins or related cyclic polyethers [20,45] were not observed for this compound, which also suggests a weak structural resemblance with 44-methylgambierone.…”
